Autodesk has recently released AutoCAD Map
3D 2016 software with an enhanced Hardware Acceleration option, refer to Figure 1. It gives the user
a stunning visual experience to move or copy large datasets. In the latest
edition of AutoCAD Map 3D 2016, a High Quality Geometry (for
capable devices) option, as shown in Figure 1 has been introduced to create high quality curves and
lineweights, and to automatically turn on the Smooth Line Display option.

Pictometry, developed by
Pictometry International Corporation, USA, is an emerging technology
used for collecting aerial imagery and data by using drones. The
pictometry imagery integrated with various GIS software is then used for
various commercial, government, infrastructural, and international
purposes.
Pictometry provides 1 foot or 6 inch
natural color images depicting up to 12 oblique views shot from a 40
degree angle as well as an orthogonal (overhead) view of every location
flown. These views can then be stitched together to create composite
aerial maps that seamlessly span many miles of terrain.

Since the shots are taken from an
angle, the pixels associated with Pictometry images are trapezoidal,
rather than rectangular. This powerful visual intelligence when combined
with the provided measuring and analytical tools leads to an efficient
and accurate inspection and assessment of any resource.

Spatial Analysis
is a technique that professionals use to extract information from large amount
of geographical data, map them in digital format, and then display them on maps,
as shown in Figure 1. It can analyze business data, health data, environmental
data, the data fire fighters use for finding shortest path in case of
emergencies, and other such data. Spatial Analysis deals with large database
and is a powerful tool that can be helpful in day to day activity such as location-allocation
study, spatial relationship, etc.

Geographical
Information System provides various components to manage spatial data, compute
spatial relationships such as distance, connectivity and directional
relationships between spatial objects, and visualize both the raw data and
spatial analytic results within a cartographic context. A user can view, plot,
understand, and query the spatial database using a GIS platform.

In AutoCAD Map 3D 2015, the map tools status bar has been
modified to the AutoCAD Status Bar. This gives more display area to work with
your drawing. It looks more suitable for the drawing window and command prompt
line. You can turn on or off status bar options by using the Customization
button available at the right side of the Status Bar.

Exploring AutoCAD Map 3D 2015 is
a textbook that has been written considering the needs of the users who wish to
learn and develop their skills in using AutoCAD Map 3D.

The book is
composed of 11 chapters arranged in a pedagogical sequence covering the basic
as well as advanced GIS concepts. In addition, this book contains a student
project, based on the real world scenario, which allows you to practice your
spatial analysis skills.
